Tennis players in quarantine hotels preparing for the Australian Open have been warned not to feed or interact with mice.
Victoria state police minister Lisa Neville "encouraged" players to "minimise interaction" with the mice, the BBC reports.
"As I understand, there may have been some feeding going on," Neville added said yesterday.
"We will keep doing pest control if we need to, but hopefully that pest control work that was done this week will have fixed the problem."
Neville confirmed yesterday three new positive cases of Covid-19 related to the Australia Open had been detected, adding that authorities are "very confident" one of the cases is a tennis player who is shedding the virus and is not infectious.
